First, the debts, expenses (last medical bills, funeral home, etc), and costs of administration of the estate need to be satisfied. Next, specific bequests are satisfied (i.e., the 3k to the cousin). Then anything that is left (ie, the " remainder") goes to the remaindermen (ie, you and your sibling). HOWEVER, the situation is complicated by an omitted spouse, who has the right to elect against the will and take 1/3 of the augmented estate.
The best resolution would be for ALL of the beneficiaries (and the wife) to reach an agreement on the distribution and settle it that way since it is such a small estate. I would really encourage you to make an appointment with a probate attorney in your area as soon as possible.

The answer given does not imply that an attorney-client relationship has been established and your best course of action is to have legal representation in this matter.
